Filed: 1988-06-24
Abstract: PURPOSE:To facilitate the manufacture of a capacitor whose capacitance is not dispersed and to evade the fluctuation of the oscillated frequency and the oscillated voltage by assembling the capacitor to the oscillator. CONSTITUTION:The capacitor is assembled to the oscillator main body. A capacitor base 7 having a prescribed dielectric constant is arranged closely beneath electrode plates 2, 2'. Two capacitors are formed by providing a couple of split electrodes 8, 8' with a proper interval to the upper face close to the lower side ridge of the electrodes 2, 2' and by providing a common electrode 10 opposite at the lower face to the electrode 8, 8' of the capacitor base 7. Then the parts of the outer side ridge of the split electrodes 8, 8' and the lower side ridge of the electrode plates 2, 2' corresponding to the electrodes 8, 8' are adhered by conductive adhesives 9, 9'. Thus, the capacitor whose capacitance is not dispersed is formed easily and the fluctuation of the oscillated frequency and the oscillated voltage is not caused.

Abstract: PURPOSE:To obtain the photodiode module low in distortion by providing a light shielding mask having a hole of a size of about the beam diameter radiated to a photodetecting area of a photodiode. CONSTITUTION:Light emitted from an optical fiber 1 is formed to parallel beams by radiating light condensed a little larger than the diameter of a hole 7a to a light shielding mask 7 having the hole 7a of a photodetecting part area or so of a photodiode chip 2 attached to the upper face of a glass window of the upper face of a cap by a selfoc lens 8, and the photodetecting part of the photodiode chip 2 is irradiated uniformly therewith.

Abstract: PURPOSE:To obtain a thin-walled and lightweight metallic pipe, by forming one end of the short-sized metallic pipe into a thick-walled and expanded radius part and forming a locking flange part at the peripheral edge of the expanded part, and drawing the remaining part in the axial direction. CONSTITUTION:A metallic pipe 8 is pressed into the 1st die hole 6 of the 1st die 7 having an expanded radius part 5 at its upper opening surface, by a punch 9 in a cold state. The upper end part of a pipe 8a is formed into an expanded radius part and a locking flange part 10 projecting outward from the peripheral edge of the expanded part is formed, and the lower part of the pipe is drawn into a small diametral one along the die hole 6. Next, the pipe 8a is pressed in a cold state into the 2nd die, thereby the inner peripheral surface of it is formed into the thin-walled shape by expanding it radially and the pipe is simultaneously formed into the prescribed length by stretching it in the axial direction. In this case, the pipe part excluding the expanded part is surely drawn, because the lockiing flange part 10 is locked at the upper surface of the die while the drawing is performed. Next, the inner peripheral surface is formed into the specular surface by performing the drawing with the 3rd die. The flange part 10 is removed at the final finishing stage after forming, and a machining such as threading is executed.

Title: Shifting arithmetic unit
Inventor: SUGIYAMA SATORU
IPC: G06F5/01
Filed: 1989-06-21
Abstract: PURPOSE:To reduce the number of operation steps and to improve an arithmetic speed by executing single precision shifting operation using a multiplexer simultaneously with single decision shifting operation in case of executing the shifting operation of data with a large bit length such as double precision. CONSTITUTION:If m > N is formed when the left arithmetic shift of double precision data of 2N bits is (m), the data of lower N bits stored in a register 4a is shifted to the left only by a number (N - m) stored in a register 4b through a shifter 1 and the shifted value is stored in a register 4c. Then, '0' is outputted to the register 4. If m < N, the data of lower N bits are shifted to the right only by (N - m) through the shifter 1, the shifted output is stored in a Q register 4d and the multiplexer 2 multiplies the lower N bits in the register 4 by a value obtained by converting the shifting number stored in the register 4b into 2's factorial by a decoder 3 and stores the multiplied value in the register 4c. Then, the upper N bits in the register 4a are right shifted only by (m) stored in the register 4b through the shifter 1 and the OR operation between the shifter output and the output of the register 4d is found out by an OR circuit 5 and the OR result is stored in the register 4c. Thus, the arithmetic speed can be improved by the constitution.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To stabilize combustion even when either of a supercharge pressure solenoid for regulating supercharge pressure and a pressure sensor for detecting the pressure in an intake passage fails down. SOLUTION: A supercharge pressure solenoid 37 regulates the supercharge pressure in an intake passage, and a pressure sensor 38 detects the pressure of intake air in the intake passage. A determination of whether the supercharge pressure solenoid 37 fails down or not is made by a supercharge-pressure- solenoid failure determination part 62b in accordance with a solenoid-operation detection signal 72, while a determination of whether the pressure sensor 38 fails down or not is made by a pressure-sensor failure determination part 62c in accordance with a signal from the pressure sensor 38. The type of engine combustion is set in such a way that a combustion type setting part 62a sends out an operation signal to injectors 41 and 42 in dependence on the engine operating condition. When either of the supercharge pressure solenoid 37 and the pressure sensor 38 fails down, the combustion type setting part 62a outputs a signal to set homogeneous combustion.
